สรุป	Concurrent case-focused mixed methods is a research design in which quantitative and qualitative data are collected simultaneously — rather than in sequence — and both strands are anchored within one or more bounded cases (e.g., a school, a program, a community, or an organisation). The two data strands are analyzed separately, then merged or compared to produce a fuller, case-grounded understanding than either strand could yield alone.	The concurrent triangulation mixed methods design collects quantitative and qualitative data simultaneously, analyzes each strand independently, and then merges the results to assess whether the two data sources corroborate one another. Often called the convergent parallel design, it is one of the foundational configurations in mixed methods research and is chosen specifically when the researcher wants to cross-validate or triangulate findings from two distinct methodological traditions.
